Mid-September 2010 SST Anomaly Update

####################
NOTE: The weekly OI.v2 SST data is available in two periods through the NOAA NOMADS website, from November 1981 to 1989, and from 1990 to present. The mid-month posts now include the full term of the NINO3.4 and Global SST anomalies from 1990 to present and a shorter-term view from 2004 to present to make the recent wiggles easier to see.

COMPARISON TO PAST LA NIÑA EVENTS AND TRANSITIONS
And for those wondering where the present NINO3.4 SST anomalies stack up against past La Niña events, I’ve provided the following comparison. I’ve also provided a comparison of the declines in global SST anomalies in response to the transitions from El Niño to La Niña, using the same years. Note that the first SST anomaly reading for each year has been zeroed, and that all global SST anomalies have been shifted accordingly. The decline in 2010 Global SST anomalies is toward the high side of the mid-range of past events.http://i51.tinypic.com/n3lz54.jpg

Would it be possible to get the current chart link for South Pacific SST Anomalies (OI.v2)from '89 to present? Would think that the trend for NINOS3.4 for the next 30 days is still down based on your last showing on Sep6 for August SST Anomolies.

Tried to go there and get the data but was unable to come up with the update using the coordinates you had for South Pacific --my fault I'm sure.

Don't mean to be pain. Still thinking that South Pacific SST Anomalies (OI.v2)from '89 to present can give the trend for NINOS3.4 for the next 30 days (up of down). Maybe not. Instead of a big chunk of S.Pac., at least the chunk below the NINOS3.4 slice of it if GOC is coming from that direction. (Similar to gauging Arctic trend from N.Atl GOC data.)

Seems GOC, at least from where the current is coming from, can give some forecast info regarding the area where the current is flowing into.

Thanks for any help and time.

PS- coordinates? same you used for South Pac on- http://bobtisdale.blogspot.com/2010/09/august-2010-sst-anomaly-update.html

Pascvaks: Are you looking for WEEKLY South Atlantic SST anomalies, since 1990, with the coordinates 60S-0, 145E-70W? I'd be happy to plot you a graph (once).

But if you're going to research things, you need to make the available tools work. Crossing 180 deg longitude may have been your problem. For input to the NOMADS (Lat, Lat, Long, Long) fields the coordinates for the South Pacific would be -60, 0, 145, 290. Or you could input -60, 0, -215, -70 and get the same output. And don't forget to select anomalies.

Comments that are political in nature or that have nothing to do with the post will be deleted.####The Smith and Reynolds SST Posts DOES NOT LIST ALL SST POSTS. I stopped using ERSST.v2 data for SST when NOAA deleted it from NOMADS early in 2009.

Please use the search feature in the upper left-hand corner of the page for posts on specific subjects.####NOTE: I’ve discovered that some of the links to older posts provide blank pages. While it’s possible to access that post by scrolling through the history, that’s time consuming. There’s a quick fix for the problem, so if you run into an absent post, please advise me.
